Am trying to make up my mind with what front-end framework(s) to use for the next few years. I see many cool ones (BS, material etc...) but hard to make up our mind to decide on which path. We have been using our custom styling and JS components for many years. It’s time to get rid of that and move towards more responsiveness and modern design.

Two important things we want to achieve, modern design. Stable JS library and actively being developed and improved.

From your experience which framework would migrate to and why?

Thx!
